When trying to run a new workflow with some jobs on macos-10.15, those jobs are just sitting saying
Found online and idle hosted runner(s) in the current repository’s organization account that matches the required labels: ‘macos-10.15’
Waiting for a hosted runner in ‘organization’ to pick this job…
However, I’m not aware of our organisation using any self-hosted runners, and our billing plan doesn’t event allow it (“Organization self-hosted runners are not available for organizations on legacy per-repository billing plans”). How can I stop this rogue runner so that Github’s hosted runners will pick up the job?
